Building Metadata-Driven Domain-Centric Routing for API Gateways
Modern API integration landscapes often end up fragmented:
- Proxy-per-backend systems
- Exploding configuration artifacts
- Frequent redeploys for every service change
- Tight coupling between routing logic and vendor platforms
The Problem
Continuously rebuilding proxy layers leads to operational overhead and limits agility.
Gateway Domain-Centric Routing (GDCR)
A vendor‑neutral, metadata‑driven approach that separates:
- Immutable execution plane (proxies + routing engine)
- Mutable control plane (metadata + routing definitions)
Instead of modifying routing proxies or redeploying when new backends or vendors are introduced, the routing engine reads updated metadata and resolves requests according to business‑domain semantics.
Validation Results
The model was validated across multiple platforms (Kong, SAP BTP, AWS, Azure) using SAP CPI as backend. Over 1,499,869 requests were processed with:
- ✅ 99.9916 % end‑to‑end success
- ✅ 100 % routing resolution success (zero routing failures)
The full paper defines the routing lifecycle, action normalization, metadata strategy, and design principles.
